Implied Closeness of Roy Oswalt trade

MLB: A deal for Roy Owaslt may be more about next year than this year for Philly - ESPN:
"Roy Oswalt has wanted a chance to play for a winner, and he mused to a friend earlier this year that he wants what Roy Halladay got in the offseason -- a chance to land with a team capable of winning the World Series. And so it could be that today or tomorrow, if the Phillies and Astros work out a tentative agreement for the right-hander, Oswalt will have a chance to accept or reject the exact opportunity that Halladay had -- to pitch for the Philadelphia Phillies
.
In order to make this happen, and to balance out their budget numbers, the Phillies are in simultaneous talks with the Tampa Bay Rays about outfielder Jayson Werth."
